SPECIFICATION forming part of Letters Patent No. 252,825, dated January24, 1882.

Application filed May 14, 1881. (N0 model.)

To all whom tt may concern:

Be it known that I, JEROME W. WETMORE, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented a new and useful Improvement in Longitudinal Torsion-Springsfor Wagons and Buggies, of which the following is a specification.

My invention relates tolongitudiual torsionsprings for vehicles; and theobject of myimprovement is to make a spring-steel side bar or otherconnecting-bar serve the purpose of a spring as well as a side orconnecting bar. I.

attain this object by the devices illustrated in the accompanyingdrawings, in which- Figure 1 is-a perspective view; Fig. 2, a verticalsection viewed from the planeacx; Fig. 3, an enlarged view of the end ofthe spring in its seat on the axle or bolster; Fig. 4, a view of thesame seat for the spring; Fig. 5, a view of the clip for holding thespring in its seat; Fig. 7, an end view of the body of the buggy placedover the spring with the arm corresponding to d fastened to the bottomand projecting down to the hinge. Theuse of this figure is to show thatI do not confine myself to the longitudinal torsion-spring as a sidebarspring. Fig.8 is a horizontal section in the plane y y, Fig. 6, showingthe widening of the slot from the middle.

(1, Fig. 6, is the end of the strap, which is bolted to the bottom ofthe vehicle. (Seen in Fig. 1, where the box and springs are brokenaway.) Instead of this may be used the halfelliptical spring, fastenedin the usual way to the bottom of the body, or the arm of atorsionspring so fastened.

The ends of the spring 6 6 may be attached to ha-lfelliptical springs onthe axle or bolster.

The vertical bar 6 e is fastened to the central cross-bar,f. Therivethead at the middle of the bar ee indicates this fastening; but toprevent the bar from being drilled and weakened a clip will connect fand e e. The horizontal bang is not fastened to cross-bar f.

The spring 0 6 may be used without the bar g. This bar g is designed toprevent the excessive side motion of the body of the vehicle. It willyield in its seat sufficiently not to resist the downward motion of thearms I) 1) against the torsional force of the spring 0 c. It is anarrower and thinner spring-bar placed very near to e e. ff, Fig. 2, isusually bolted to the reach k. This central cross-bar,f, holds themiddle points of the springs e 6, so that. the torsional force of eacharm I) b on the spring ends atf, making 0 0 equivalent to two springs.

A lip on the back side of the blocks, Figs. 3 and 4, is bent down like aflange over the edge of the axle or bo'ster, between the ears i i, Fig.5.

What I claim is- 1. The vertical or oblique spring side bar, 6 6, whensustained in the middle and at each end without pivot-bearings, incombination with the arms I) I), counectingit with the body of thevehicle, substantially as described.

2. The oblique or vertical spring side bar, 0 e, sustained in the middleand at each end without pivot-bearings, in combination with thehorizontal spring-bar g and arms I) 1), constructed and arrangedsubstantially as described.
